Sorry, I have never tried the Devacurl line. This is what I do. I almost daily CO wash with VO5 or Suave conditioners. Every couple of weeks (or sooner if my hair feels blah or producty) I shampoo with Isoplus Conditioning shampoo and do an ACV rinse. I follow this up with a semi DT type of thing.

hi, i'll not be able to shampoo once or twice a month. maybe coz of the weather here [humid etc.]. i find that even when i just wet & condition, the scalp gets oily after a few days, which i don't like.

currently i'm on low-poo and a lot of conditioner. i fear how quickly my bottles of conditioner might have to be replaced once my hair gets longer
